OPTSICOM
Rafa Martí and Abraham Duarte coordinate the OPTSICOM research project with 11 members in 2 universities. The acronym stands for
Optimization of Complex Systems. In this project we develop algorithms, based on metaheuristic methods,
which integrated in a software, solve hard optimization problems. It has
been funded by the Spanish Goverment for more than 10 years, currently with the code PGC2018-095322-B-C21 (2019-2021).
In the OPTSICOM website, codes, instances and best known solutions for the problems in which we are working are available.
You can directly download from here the LOLIB and
MDPLIB.
